Re: [beagleboard] Question regarding UART

Which programming language would be the best to write uart applications in
C++, Python, or Java?

This question doesn't make any sense. There is not a better programming
language than another.Not absolutely. From your question I can understand
that you are pretty new in the world of programming. Specially for embedded
devices. Maybe you want to use the BBB and not be one day an expert in
informatics. In this case you can start which any language you want, but
most probably you'll find confortable with Python.
In this case you have tons of tutorial about using USART. But...if you
don't have any experience in programming language it will be very hard for
you to adapt tutorials to your needs.

Is it possible to send data between the uarts without them being physically
connected?

Do you mean through a wireless connections? Of course...take a look at Xbee
Module or eNIC Nitro. The latter is a modified version of an Arduino. Both
are really easy to configure and to use.

Google. Seriously.

No . . . and yes. No, they must be connected in order to communicate with
one another. Yes, in that there is wireless UART through bluetooth. I do
not know much about though other than it exists, but you can find serial to
bluetooth adapters on ebay all day long for ~$3 USD each.

[beagleboard] Question regarding UART

2016-01-19 Thread Michael Williams 
I have a few questions regarding the UARTs on the Beaglebone Black & Green.

What is a good resource for writing programs for the uarts? Which 
programming language would be the best to write uart applications in C++, 
Python, or Java?

Is it possible to send data between the uarts without them being physically 
connected?  

Thank you in advance for your help.

Mike

BY the way, "which language?" is subjective, and something you need to
answer for yourself. Me ? I prefer C, but I always prefer C.

The question is valid, and makes perfect sense. However the answer is
largely subject to opinion.

So, in Linux, a serial device generally presents it's self as a file
object. Like so many other devices in Linux. What this means is that any
language that has libraries, or APIs for handling files can be used to
communicate over serial. Also, since maximum theoretical communication
speed for UART is around 3Mbit / s(reliable ), having the fastest language
such as C, or C++ in play does not matter so much. For this one small
aspect, at any rate. However, if the application does much more than just
some form of serial communication + storing data. C / C++ might be a good
idea.

For communication over serial, and data visualization though, even
Javascript can be used ( Nodejs ), and in fact it's been proven time, and
time again. That Nodejs is often more performant when compared to most
scripting languages. But gain, I digress. Performance is very possibly a
minor concern here . . .
